Conductive polyaniline helixes self-assembled in the absence of chiral dopant.

The morphological evolution of PANI helixes was achieved without the use of chiral dopants, but by a facile process through the generation of onion-like multi-lamellar vesicles used as a novel soft-template and a liquid crystal acting as a promoter for PANI polymerization and self-assembly, which is a breakthrough for the synthesis of helical structures.
